Michigan State football staff adds former Ohio State assistant

EAST LANSING (AP) -- Michigan State football coach Mark Dantonio has added former Ohio State assistant Jim Bollman to his shuffled staff.

Dantonio announced Monday that Bollman has been hired as co-offensive coordinator and tight ends coach. Bollman leaves Purdue, where he was hired last month to be its offensive line coach after working last year at Boston College.

He previously worked with Dantonio at Ohio State, Youngstown State and with the Spartans when they both were assistants for Nick Saban.

Michigan State also gave defensive coordinator Pat Narduzzi the title of assistant head coach. Dave Warner becomes a co-offensive coordinator and shifts to coaching the running backs after previously being the team's quarterbacks coach. Brad Salem moves from coaching running backs to quarterbacks along with being the recruiting coordinator.
